Real-time Group Refractive Index Measurement Of Fluids Using Interferometry

Posted June 21, 2017 by Kristin

Abstract — Maintaining proper chemical composition of fluids is an important control parameter for a variety of different production processes. This is especially critical in the medical device manufacturing to maintain high quality standards. One method to monitor fluid composition is to measure its refractive index.

Lumetrics offers a commercial low-coherence interferometer, the OptiGauge II. Combined with custom software, the group refractive indices of fluids can be quickly and accurately measured, on- or off-line.
